Argentina Expands Hantavirus Investigation After Cruise Ship Outbreak

Argentine health authorities are expanding their investigation into a hantavirus outbreak that occurred aboard the cruise ship Hondius. Following thirteen confirmed cases and three deaths, researchers are now analyzing rodents in Mendoza and Ushuaia, collaborating with the U.S. Centers for Disease Control and Prevention (CDC) to determine the virus’s origin.

What happened aboard the cruise ship Hondius?

An outbreak of hantavirus was confirmed among passengers and crew on the Hondius during a voyage from Argentina to Cape Verde. According to official reports, thirteen cases were confirmed in total.

The outbreak resulted in three deaths, including two Dutch nationals. While the impact is documented, the exact origin of the virus remains unclear.

Did You Know? In mid-May, researchers captured more than 150 rodents in the vicinity of Ushuaia, the southern city where the Hondius departed in April.

Why is the investigation expanding to Mendoza?

Health authorities are extending their search for the virus’s source to the western province of Mendoza. A targeted operation to catch and analyze rats is scheduled for June 8 to 12.

While no cases of the Andes variant of the virus have been detected in Mendoza so far, the University of Mendoza recently issued a report stating that “the risk is not zero.”

Expert Insight: Samantha Carter notes that the decision to monitor a region with no confirmed cases suggests a precautionary approach to prevent future transmission. By involving the CDC, Argentina is leveraging international expertise to map the potential geographic spread of the Andes variant.

What may happen next in the investigation?

Argentine biologists and the U.S. CDC may identify the specific strain of the virus through the ongoing analysis of samples from Ushuaia and Mendoza. This collaboration is likely to focus on whether the rodents in these regions carry the same variant found on the ship.

If the Mendoza operation yields positive results, it could shift the understanding of where the virus is present in the country. This may lead to further rodent sampling in other provinces to fully map the risk.
